This issue was found while fuzzing the new backend (#2453); I suspect
that it arises with the new backend because we can sink instructions
(e.g. loads or extends) in more interesting ways than before, but I'm
not entirely sure.Test coverage will be via the fuzz corpus once #2453 lands.

Sort by generated-code offset to maintain invariant and avoid gimli
panic.Fix srcloc interaction with branch peephole optimization in
MachBuffer: if a srcloc range overlaps with a branch that is
truncated, remove that srcloc range.These issues were found while fuzzing the new backend (#2453); I suspect
that they arise with the new backend because we can sink instructions
(e.g. loads or extends) in more interesting ways than before, but I'm
not entirely sure.Test coverage will be via the fuzz corpus once #2453 lands.
